Investment by a pvt ltd company in a partnership firm

Yes. A company can invest in a partnership firm's business and for making investment it is not necessary for the company to become partner.

I donot wish to render any advice to "Perfect Solutions".

It is by way of corporate loan.

The company wants to invest by way of giving a corporate loan to a partnership firm in which a director is a partner.

As per section 185 of Companies Act 2013, the company can not give loan to a firm in which a director is interested. Please correct me if i am worng. Is there any way the company can provide loan by passing a special resolution or something?

Thanks.
